Buffalo SATA II 4TB Replacement Hard Drive HDD for DriveStation Quad Gen2 Storage Solution

The Buffalo OP-HD4.0QH is a 4TB replacement hard drive created for anyone who relies on a DriveStation Quad Gen2 and needs to add space or swap out a tired disk without breaking stride. By delivering a roomy four-terabyte capacity, the drive gives photographers, video editors, and small business owners the breathing room they need for raw footage, project files, or daily backups.

Because the drive uses a SATA II interface, it plugs directly into the DriveStation Quad Gen2 backplane and moves data at a rate that keeps large transfers from slowing down your workflow. Its 3.5-inch form factor matches the physical bay already in your enclosure, so installation is a straightforward slide and click with no adapters or extra cables.

Buffalo builds this drive for NAS-grade duty cycles. That means it is engineered to spin for long stretches, handle the cooling profile of a multi-bay chassis, and stay consistent under the stop-start traffic typical of a shared office server or a home media library. Whether you are archiving family photos, hosting a Plex library, or running nightly backups for client documents, the drive provides the endurance and capacity that keep data safe and easy to reach.

Buffalo also includes a three-year limited warranty. If a concern ever crops up, you have direct access to support without the uncertainty that comes with generic off-the-shelf drives. In short, the OP-HD4.0QH brings you extra space, dependable performance, and seamless compatibility with the device you already trust.

• 4TB of storage for extensive photo, video, and document libraries

• 3.5-inch size that fits the existing bay with no adapters required
